Spring is one of the most commonly used parts in the mechanical and electronic products industry. It can produce very large elastic deformation when it is loaded, and this elastic deformation also transforms mechanical work or kinetic energy into deformation energy, which can unload the change of spring, and disappear and return to the original shape, finally, finally. Transformation of deformation energy into mechanical work or kinetic energy. With the continuous progress of the times, the application of spring is very wide, the automobile, computer, TV, pin, phone, cell phone and so on are u...

Like most other basic mechanisms, metal springs have existed for a long time in the bronze age. Even for metals, wood is used as a structural member of flexible bow and arrow and military catapult. In the Renaissance, precise clocks made precision springs the first necessity. In Fourteenth Century, we saw the precise clock of revolutionary astronomical navigation developed. The world's exploration and conquest of European colonial powers continue to provide impetus for watchmakers "science and art." The other area of the firearm promotes the development of the spring.

The spring should ideally conform to hooke's law, that is, the relationship between stress and strain in the elastic range is linear.However, since the actual spring steel is a polyphase and polycrystalline material, there must be inconsistencies in composition, structure, elasticity, etc., and the stress and strain deviated from the linear relationship within the elastic range, which is called elastic incompleteness or anelastic.The phenomena such as elastic after effect, elastic lag, stress relaxation and elastic modulus decrease are produced.After tempering, the stabilization process can re...

Springs are ubiquitous in all kinds of machines—from consumer products to heavy industrial equipment, take apart anything that involves a mechanism, and chances are, you’ll find a spring inside. Springs are storage devices for mechanical energy—think of them as analogous to batteries! The earliest spring-driven clocks appeared in the 1400s. Fast-forward some 600 years, you still have to charge the Apple Watch everyday, and it’s not nearly as fast as winding a clock…but I digress.My personal fascination with springs began with Slinkies and wind-up toys, and countless mechanical pencils were sac...

A compression spring is an open-coil helical spring that offers resistance to a compressive force applied axially. They are usually coiled at a constant diameter, though they can be coiled in other needed forms such as conical, concave (barrel), convex (hourglass), or various combinations of these. Compression springs are used to resist force and/or store energy,1、CharacteristicsBy far the most widely used type of spring, compression springs are designed to oppose compression and return to its uncompressed length when the applied force is removed. 2、Service LifeIt should be noted that if critical force-versus-deflection linearity is required, only the center 60-80% of the available deflection range should be employed.Thus, reserve at least the first and last 15-20% of t...

When choosing the right spring, selecting the best spring wire is a critical before manufacturing. Below are some of the most common spring wire materials and their unique characteristics .Stainless Steel SpringsStainless steel springs have low-stress relaxation and resist corrosion. They have good strength at moderate temperatures and are resistant to heat. Extension springs are most commonly made from stainless steel.Extension springs absorb energy and provide resistance to pulling. As the name suggests, an extension spring stretches as a load is applied to it. Applications for extension springs include carburetors, trampolines and farm machinery.Oil Tempered Spring WireOil tempered wire is cold drawn and heat treated before plating.

springs are a mechanical part that use elasticity to work. Generally made of spring steel. It is widely used in machines and instruments to control the movement of machine parts, mitigate impact or vibration, store and store energy, measure force, etc.The spring is just an accumulator, it has the function of storing energy, but can not release the energy slowly, to achieve the release of this function should rely on the 'spring + large transmission ratio mechanism' to achieve, common in the mechanical table.The spring is widely used in the mechanical and electronic industry. The spring can produce a large elastic deformation under load and convert mechanical work or kinetic energy into deformation energy. After unloading, the spring's deformation disappears and returns to its original stat...
